The Astros have made a contract offer of one year with an option to free agent pitcher Charlie Morton, Bob Nightengale of USA TODAY Sports reports. The amount of the contract offer is not known, but would likely be less than the $17.9 million qualifying offer the Astros failed to make to him.

Morton, 35, had the best season of his career in 2018, going 15-3 with a 3.13 ERA and a 201/64 K/BB ratio in 167 innings. It is likely the peak in what has been a late-career reinvention that started at the end of his tenure in Pittsburgh, persisted through an injury-shortened stint with the Phillies, and continued over the last two years with the Astros. Morton’s delivery, which famously mimics that of the late Roy Halladay, has seen his strikeout rate rise from middling to elite rates while his fastball velocity climbed from the low-90’s to the mid-90’s.

Despite Morton’s reinvention, he is likely going to have to settle for short-term deals due to his age and durability issues. 2018 was the first time in his career he crossed the 30-start threshold.
